DISPLAY DEVICE.

Application filed May 7,

My invention relates to improvements in display devices, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of my invention is to provide a display device in which the exposed matter is continuously changing.

A further object of my invention s to provide a device of the type described in which the driving mechanism is simple in construction, and which is positive and smooth in operation.

A further object of my invention s to provide a device of the type described in whlch amultiplicity of displays may be brought. into view, each display being removable.

Other objects and advantages Wlll appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended cla ms.

My invention is 1llustrated 1n the accompanying drawings, forming part of this application, in which Figure 1 is a front elevation of the dev ce.

Figure 12 is an end elevation of the seg ments and the operative mechanism for moving the segments, and

Figure 13 is a detailed illustration of the hinged sides of the actuating disc.

In carrying out my invention, I provide a casing 1 having a relatively large opening 1926; Serial N0. 107,385.

2 therein. A cross bar 3 is disposed in the upper and lower portions of the casing 1. Bearings 4 and 5 are rigidly secured to the cross bars 3. Relatively short shafts 6 and 7 are rotatably mounted within the bearings 4 and 5. Upon the upper pair of shafts 6 and 7, gears 8 and 9 are rigidly mounted.

A bearing 10 is rigidly secured to the upper cross bar and provided with a shaft 11 rotatably mounted therein. A gear 12 is rigidly mounted upon the shaft 11, and is in mesh with the gears 8 and 9. A relatively small gear 13 is rigidly mounted upon the shaft 11 beneath the bearing 10. A rack 14 which is slidably disposed in supports 15. is in mesh with the gear 13.

Any suitable means may be employed for oscillating the rack 14. I have employed an arm 16 pivotally secured to the rack at 17 and to an eccentric at 18. The eccentric is rigidly mounted on a shaft 19 which is rotated by means of a motor, not shown.

The segment-moving mechanism is disposed beneath the gears 8 and'9 and the upper cross bar 3. The segment-moving mechanisms are identical in construction, and a description of one will apply to the other. A support 20 is rigidly mounted upon the shaft 6. A disc 21 having hinged sides 22 and 23 is rigidly mounted upon the support 20. The sides 22 and 23 are provided with weights 24 and 25, respectively. The side 22 is provided with a pin-release cam 26, as clearly shown in Figures 4 and 12. The side 23 is provided with a cam 27 on the upper surface thereof and a pin-engaging cam 28 integral with the under surface thereof. A pin-retaining latch 29 is pivotally mounted upon a rigid support 30 and provided with a transversely extending finger 31 which rests upon the upper surface of the disc 21 adjacent its periphery.

A multiplicity of radially extending segments 32 is vertically disposed in the casing 1 between the cross bars 3. In Figures 6 and 7, I have shown enlarged views of one of the segments. The segment comprises a frame 33 which is angular in cross section. Acarrying bar 34 is rigidly secured to the frame 33 and provided with a horizontally extending pin 35. The frame 33 is provided with a plurality of slots 36. Plates 37 having compartments 38 therein are provided with bolts 39 which are receivable in the slots 36. Either of the plates 37 may be removed from the frame without interfering with the other plate. The compartments 38 may be of various sizes and shapes to receive articles of display indicated generally at 40.

The means for supporting each of the segments consists of a bracket 41 having an opening therein adapted to receive the shaft 6, see Figure 8. A clamp 42 is disposed concentric with the carrying bar 34 and rigidly eld thereto by means of a set screw 43. The free end of the bracket 41 is turned dowrb wardly and disposed between the carrying bar 34 and the inner surface of the bracket 41 and rigidly held in place when the set screw 43 is tightened. The clamp 42 is dis posed beneath the pin 35. A like construction isprovided for each of the segments adjacent the shafts 6 and 7.

In Figure 8, I have shown an adjustable stop member which consists of two arcuateshaped members 44 and 45 provided with a plurality of openings 46. The outer ends of the members 44 and 45 are turned clownwardly so as to provide abutting surfaces 47 and 48. The stop members may be rigidly secured to any of the segments by means of screws 49 for the purpose of removing a number of the segments without interfering with the operation of the device.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. When the shaft 19 is rotated, the eccentric is actuated, thus oscillating the rack 14. As the rack is oscillated, the shaft 11 is rotated one-half revolution in one direction and one-half revolution in the opposite direction. As the gear 12 is rigidly mounted upon the shaft 11, it will be rotated in a like manner. In this manner, the gears 8 and 9, which are in mesh with the gear 12, will be simultaneously rotated one-half revolution in a clockwise direction, and one-half revolution in a counter-clockwise direction.

The shafts 6 and 7 are rigidly secured to the gears 8 and 9 and are rotated therewith. During the rotation of the shafts 6 and 7, the discs 21 are swung in a counter-clockwise direction, causing the fingers 31 of the pinretaining latches 29 to ride upon the cam 27,

thus releasing the pin 35 of the first segments 32. A continued movement of the discs 21 will cause the pm-engag1ng cams 28 to ride up and over the pins 35 of the first segments. At this point, the rotation of the discs in a counter-clockwise direction is stopped and the discs are then rotated in a clockwise direction, causing the segments 32 to be swung to the opposite side. As the segments 32 strike the segments 32 the entire groups of segments are moved until the discs have completed their one-half revolution in a clockwise direction. The pin-retaining latch 29 engages with the pin of each segment as they are moved into engagement therewith. As the discs 21 complete'their rotation in a clockwise direction, the pinrelease cams 26 will ride upon the pins 35 of the adjacentsegments, and as the discs are again rotated in a clockwise direction, the cams 26 will ride upon the pins 35 of the segments 32 and then become free to continue their movement in a counter-clockwise direction. This operation is constantly re peated until all the segments have been brought into view, and then repeated.

Advertisements may be printed or placed upon the plates 87. Articles to which these various advertisements may apply can be placed in the compartments. It will be observed that one of the plates of a segment may be removed therefrom for the purpose of changing or revising, and adiiferent plate be put in its place without the necessity of removing the other original plate. Furthermore, the plates may be arranged so as to show one relatively large display, or a plurality of relatively small displays.

I claim:

1. In a device of the character described, a multiplicity of vertically disposed segments, pins carried by said segments, a vertically disposed shaft, a support rigidly mounted upon said shaft, a disc rigidly mounted upon said support and comprising hinged sides, a pin-engaging cam integral with one of said sides, a pin-release cam integral with said other side, a pin-retaining latch, a cam carried by one of said sides for actuating said latch, and means for rotating said disc in one direction for permitting said pin-engaging cam to pass over one of said pins, said means rotating said disc in an opposite direction, whereby one of said segments is transferred from one radial extension to the opposite radial extension.

2. In a device of the character described, a pair of shafts, a gear mounted upon each of said shafts, a multiplicity of radially disposed segments pivotally secured to said shafts, means disposed above said segments for actuating said segments when said shafts are rotated, a drive shaft, agear rigidly mounted upon said drive shaft and in mesh with said first named gears, a pinion mounted upon said drive shaft, a rack in mesh with said pinion. and means for oscillating said rack, whereby said gears will be continuously rotated in a semi-circuitous path.
